Donald Trump’s candidacy and now, presidency, have resurrected a public discourse not heard in this country since the Great Depression — an anxious discourse about the possible triumph in America of a fascist-tinged authoritarian regime over liberal democracy. It’s a fear Sinclair Lewis turned into a 1935 bestselling novel, It Can’t Happen Here — although, as Lewis told it, it sure as hell could happen here.

It did not happen, however. Not then, at least. Electing Franklin Roosevelt as president and taking up the labors of the New Deal, our parents and grandparents not only rejected the sirens of authoritarianism, they actually extended and deepened American freedom, equality and democracy. They subjected big business to public account and regulation; expanded the nation’s public infrastructure and improved the environment; empowered the federal government to address the needs of working people and the poor; mobilized farmers’ organizations, labor unions, consumer campaigns and civil rights groups and fought for their rights, broadening the “We” in “We the People.”

Undeniably, they left a great deal to be done. But they gave themselves the wherewithal to defeat fascism overseas and learned how to democratically rebuild the nation.

Now we find ourselves anxiously asking, Can it happen here? Trump has given us plenty of reason to worry.
